For real. When you install a program that associates itself with image files, you may lose your thumbnails capability in Windows XP. It shows a giant icon of the program instead of the thumbnail. How to fix it? It’s elementary, Watson, Just go to Control Panel->Add or Remove Programs -> Windows components, don’t change anything and click “next” a couple of times. That’s it! The rumor goes, that if while doing that you three times say loudly “Microsoft rules”, it works even better. 🙂
